IMPROVEMENT lN LANTERNS.

The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern: i

'Be it known that I, PETER SWnnuY, of the city,

county, and State of New York, have inventeda new and useful Improvement in Lanterns and I do hereby declare the following. to be a full, clear,' and exact description thercof; which will enable those skilled in the art to makefand use the same, reference being. bad to the accompanying drawing forming part of this specification, in which drawing Figure 1 is avertical central section of a lantern, which contains, my improvement.

Figure 2 is a top view thereof.

Figure 3 is a bottom view.

Figured is a bottom view of a lantern, which contains a modification of a portion of my invention.

Figure 5 is a vertical central section of fig. 4. Similar letters-indicate corresponding parts. The letter A designates the guards which connect the upper flange B of the lantern with its body 0, the guards being connected by rings D in the usual'manner. I i i The body 0 of the lantern is hollow and open, and it is bent over at its upper part to form a flange, E, to which the lower ends of the guards A are secured, the inner edge of the bend forming a shoulder at F.

Theglobe or glass of the lantern has a vertical flange at the bottom, which fits into the body of the lantern, and above the flange the globe widens to form a shoulder, G,which rests upon the shoulder 1* in such a-manncras to give the required support to the globe. I i

The body 0 has abroad base flange, H, on which thelantern rests, and at the lower line of the verticalpart of the body I form an inside horizontal flange,

I, which is slotted at opposite points, as atJ'J,'to'1-e ccive catches or lugs K K that projectfrom the sides of the lamp L.

The bottom of the lamp is I made with a flange, M, which is made deep enough to receive and shield the handle N, by means of which the lamp is inserted and withdrawn from the body of the lantern.

The lugs K K in this example are continuations of the handle, and they are formed by bending the ends of the wire of which the handle is composed, and extending them in opposite directions through the vertical elongated slots 0 0, formed for that purpose in the flange M.

\Vhen I desire to connect the lamp with the bot? tom of the lantern, I insert itfrom below, in such a manner that. the spring lugsK enter the slotsJ J above mentioned, wl1en,-by rotating the lamp, the lugs slide on. the flange I until they come to stops 1? P.

Th pressure of the spring lugs: on the flange holds the lamp in place, and, in order to enable them to I take hold of the flange on. entering the slots, 'fben'd down the flange at the edges of the slots, so that the lugs can ride up thereon.

my spring fastening in the following manner: The supportingflange of the lantern, which, in figs;

1 2 3, is connected with the body of the lantern, here In the modification, shown in figs..4 and 5, I apply consists of the flange M of the lamp, the upperpart of which flange is slotted to receive the segmental flanges II, which projectinward from opposite points in the sides of the body G.

Under .the bottom of the lamp is a rotating plate, K, which is pivoted to it, so that it can be turned thereon by means of the handle N, and between said bottom and the rotating plate I inter-pose an elliptical spring, B, which is held bythe same pivot which I holds. saidplate.

The edge of said rotating plate is slotted at J J, in

correspondence with the slots 0 0, so that the slots can be brought to coincide with each other, and one of the edges of the slots J J is bent up in order to allow it to take hold of the segmental flanges I, which takes place if the lamp is pushed up into the body C, so that the said partsI enter the slots 0 O J J, and the plate K is then rotated, so as to carry its slots J J past the parts I, the spring R operating, as before, to hold the lamp and the body of the lantern together.

The extent of mot-ion of the rotating plate is governed by a stop-pin, S, arranged on the bottom of the lamp, and projecting through a slot, '1, in said plate;

This modification consists substantially in cutting away most of the fiangetshown at I, figs 1 and 2, and substituting the spring rotating plate Kfor the spring lugs or catches K. i My invention also relates to improvements in the top part of the lantern, as will benext described.

Theiupper flange B of the lantern is made with a large internal diameter, for the purpose of introducing the globe or glass into the lantern from above. The top of the globe or glass is then held securely by a cap, U, which is so made as also to form the top of the lantern.

The cap is made with a bottom flange, 'V, which rests on the flange B, and its edge is slotted at WW to allow bent catches or hooks X X, which rise from the flange, to enter said slots, and become engaged by the edge of the flange V, when the cap is rotated, the extent of its rotation being limited by a stop, Y, formed on said flange, which strikes one of the books.

It will be seen that the hooks X are continuatioiis of the guards A beyond the flange B. These books, in connection with the slot-ted flange, form a simple and durable fastening fort-he cap U,

If the books were separate, and rivetedor soldered to the flange, the cost of the lantern .is 'ncreased. Besides this, it they are riveted, their heads wear and become loose, and the hooks turn, or, if soldered, the slotted flange I of the body Got the lantern, subheat from the lamp causes the solder to flow, and stantially as described. V thus, in either case, the fastening becomes insecure. 2. The guards A A, continued beyond the flange The cap is prevented from beingshakeu loose by a B into hooks X, in combination with the slotted spring, Z, fastened on the under side of flange B, and flange V of cap U, substantially as and for the purwhose free end is arranged to work up through a slot, pose described.

so as to bear against the under side of the cap; This specification signed by me this 11th day of What Iclaim as new, and desire to secure by Let- July, 1870.
